Married at First Sight's Tracey has opened up about her post-baby health scare.

We were first introduced to Tracey Jewel as a single mum looking for love on Australia’s favourite fake-marrying reality TV show, Married At First Sight.

Tracey’s time on the show was turbulent at best. She was cheated on by her fake husband, Dean Wells, and after the show wrapped up, she started dating fellow contestant Sean Thomsen.

Now Tracey has shared another heartbreak from her past.

On Saturday, the 34-year-old told her fans on Instagram about her brush with cervical cancer when she posted a photo of her new hair extensions.

What an amazing day that was and what a beautiful wedding! #brissy #vaycay #wedding #loveintheair #laughs???? @seanythomsen ????

“I’ve been getting my @greatlengthsaus hair extensions from my gorgeous friend @naomipanizza_thestudio for years! (Hair never grows back after cervical cancer the same way) thank you for always being so amazing and making my hair look fabulous!,” the reality TV star captioned her post.

Tracey later told the Daily Mail, her doctors discovered she had CIN3 cervical cancer cells six weeks after she had given birth to her daughter Grace.

“I had to have a operation to remove the lesions straight away and then couldn’t breastfeed which was devastating to me,” she explained.

The mum-of-one also told the publication she now has regular pap smears to keep on eye on her abnormal cell problems. Her daughter Grace is now eight years old.

This news came after Tracey had announced on Instagram she was auctioning off her MAFS wedding dress to raise money for a domestic violence charity.

“Well since I’m not with Dean anymore, why not,” she told the Daily Mail.

All proceeds from the auction will go to Momentum Forum Events and Kiss Violence Against Women Goodbye.
